Introduction

The AWS Certified Solutions Architect – Associate (SAA-C02) exam is intended for individuals who perform in a solutions architect role. The exam validates a candidate’s ability to design secure and robust solutions by using AWS technologies.

The exam also validates a candidate’s ability to complete the following tasks:
 Design a solution by using appropriate AWS services and by following architectural principles based on requirements
 Provide implementation guidance based on best practices to the organization throughout the workload lifecycle

Target candidate description

The target candidate should have at least 1 year of hands-on experience designing secure, highperforming, cost-effective, highly available, and scalable systems by using AWS services.

Recommended AWS knowledge

The target candidate should have the following knowledge:
 Hands-on experience using compute, networking, storage, management, and database AWS services
 The ability to identify and define technical requirements for a solution that involves AWS technology
 The ability to identify which AWS services meet a given technical requirement
 An understanding of best practices for building well-architected solutions on AWS
 An understanding of the AWS global infrastructure
 An understanding of AWS security services and features in relation to traditional services

What is considered out of scope for the target candidate?

The following is a non-exhaustive list of related job tasks that the target candidate is not expected to be able to perform. - These items are out of scope for the exam:
 Design a complex, hybrid network architecture
 Design identity federation within multiple accounts
 Design an architecture that meets compliance requirements
 Incorporate specialized services in a design
 Develop deployment strategies
 Create a migration strategy for complex multi-tier applications

Exam content

Response types

There are two types of questions on the exam:
 Multiple choice: Has one correct response and three incorrect responses (distractors)
 Multiple response: Has two or more correct responses out of five or more response options
Select one or more responses that best complete the statement or answer the question. Distractors, or incorrect answers, are response options that a candidate with incomplete knowledge or skill might choose.
Distractors are generally plausible responses that match the content area. Unanswered questions are scored as incorrect; there is no penalty for guessing. The exam includes 50 questions that will affect your score.

Unscored content

The exam includes 15 unscored questions that do not affect your score. AWS collects information about candidate performance on these unscored questions to evaluate these questions for future use as scored questions. These unscored questions are not identified on the exam.

Exam results

The AWS Certified Solutions Architect – Associate exam is a pass or fail exam. The exam is scored against a minimum standard established by AWS professionals who follow certification industry best practices and guidelines. Your results for the exam are reported as a scaled score of 100–1,000. The minimum passing score is 720.
Your score shows how you performed on the exam as a whole and whether or not you passed. Scaled scoring models help equate scores across multiple exam forms that might have slightly different difficulty levels. Your score report could contain a table of classifications of your performance at each section level. This information provides general feedback about your exam performance.
The exam uses a compensatory scoring model, which means that you do not need to achieve a passing score in each section. You need to pass only the overall exam.
Each section of the exam has a specific weighting, so some sections have more questions than other sections have. The table contains general information that highlights your strengths and weaknesses. Use caution when interpreting section-level feedback.

Content outline

This exam guide includes weightings, test domains, and objectives for the exam. It is not a comprehensive listing of the content on the exam. However, additional context for each of the objectives is available to help guide your preparation for the exam. The following table lists the main content domains and their weightings. The table precedes the complete exam content outline, which includes the additional context. The percentage in each domain represents only scored content.
